The pie chart illustrates how the four key causes (deforestation, over-grazing, over-cultivation, and others) have resulted in the loss of Farming land’s productivity during the 1990s. The table indicates the percentage of land degraded in three different regions of the world due to the above causes.

The pie chart illustrates how the four key causes (deforestation, over-grazing, over-cultivation, and others) have resulted in the loss of Farming land’s productivity during the 1990s. The table indicates the percentage of land degraded in three different regions of the world due to the above causes. Overall, over-grazing has resulted in most of the land degradation followed by deforestation, and over-cultivation. However, the difference in their share of destruction is very minute. On the other hand, Europe stands as the most affected with North America being the least while Oceania takes up the second place. To begin with, Overgrazing has resulted in more than one third’s (35%) of the soil turning less useful, followed by deforestation and overcultivation accounting for 30% and 28% respectively. Other causes made up only 7%. To finalize, the total land that lost its productivity was the highest (23%) in Europe region where deforestation, overcultivation, and overgrazing made up 9. 8%, 7. 7% and 5. 5% respectively. By contrast, the same figures in case of Oceania stood at 1. 7%, 0, and 11. 3% with 13% of the overall land loosing its productivity. The least prone region was the North America with only 5% of its soil losing fertility which was a result of 0. 2% from deforestation, 3. 3% from Overcultivation and just 1. 5% from overgrazing.
